陕西省2005-2019年乙型病毒性肝炎重复报告情况分析

目的 对陕西省2005-2019年乙型病毒性肝炎（乙肝）重复报告情况进行分析，剔除重复报告卡，获得陕西省乙肝调整报告发病率，比较我省乙肝查重系统运行前后重卡率和重卡数，评价乙肝查重系统使用效果。方法 收集陕西省2005－2019年乙肝报告卡，利用R3.5.1软件的sqldf包调用SQL语句分析乙肝重复报告情况。结果 2005-2019年陕西省共报告乙肝463121例，其中急性51980例，慢性271647例，未分类139494例。临床诊断病例55082例，确诊病例408039例。2016年前年内重卡数呈上升趋势，2017年后年内重卡数趋于稳定，年内重卡率总体呈小幅上升趋势。陕西省2005-2019年乙肝累计重卡数为31978张，累计重卡率为6.90%，累计重卡率平均增长率在2017年后明显下降。跨年重卡数2016年前呈明显上升趋势，2017年跨年重卡数较之前明显减少。2005-2019陕西省乙肝平均报告发病率为81.99/10万，调整后乙肝平均报告发病率为75.78/10万。结论 重复报告使乙肝报告发病率被高估，应探索乙肝报告管理新模式，充分利用乙肝查重系统，提高监测数据质量。

Hepatitis B duplicate reporting cards in Shaanxi, 2005-2019

To get the adjusted incidence rate of hepatitis B in Shaanxi Province，and to analyze the duplicatereporting hepatitis B cards in Shaanxi Province from 2005 to 2019. To compare the rate of hepatitis B duplicate reporting cardsbefore and after hepatitis B duplicate report checking system used in Shaanxi Province，so as to evaluate the effect of hepatitisB duplicate report checking system in Shaanxi Province. Methods The hepatitis B report cards of Shaanxi Province from 2005to 2019 were collected，SQL statements called by sqldf package of Ｒ3. 5. 1 software were used to analyze the duplicate reportinghepatitis B cards in Shaanxi Province from 2005 to 2019. Ｒesults A total of 463 121 hepatitis B cases were reported inShaanxi Province，including 51，980 acute hepatitis B cases，271，647 chronic hepatitis B cases，and 139 494 unclassifiedhepatitis B cases. There were 55，082 clinical diagnosed hepatitis B cases and 408，039 confirmed hepatitis B cases. Before2016，the number of duplicate reporting hepatitis B cards during the year showed an upward trend，which tended to be stableafter 2017. Overall，the rate of duplicate reporting hepatitis B cards during the year showed a slight upward trend. The numberof accumulative duplicates reporting hepatitis B cards from 2005 to 2019 in Shaanxi Province was 31，978，and the rate ofaccumulative duplicate reporting hepatitis B cards was 6. 90% . The average growth rate of accumulative hepatitis B duplicatereporting cards decreased significantly after 2017. From 2005 to 2016，the number of multi － year duplicate reporting hepatitisB cards showed a significant upward trend，since 2017，the number decreased significantly. From 2005 to 2019，the averagehepatitis B incidence in Shaanxi Province was 81. 99 per 100，000，and the adjusted average hepatitis B incidence was 75. 78per 100，000. Conclusion The report incidence rate of hepatitis B is overestimated because of the duplicate reports. The newmodel of hepatitis B report and management should be explored and the hepatitis B duplicate report checking system should bewell used to improve the quality of monitoring data
